I've got a server running Nt4.0 server and exchange 5.5 Out of nowhere, nobody could access their inbox. When i looked at the server, an error was on the screen talking about a driver or service failing to load. The event viewer had 3 errors in it along the lines of 1). Database in inconsistent state initilizing the Ms.Exch.server information store database, 2). unable to initilize the Ms Exch. information store service,and 3). Unable to get the appletalk network address of the Ms. Exch. servercomputer.
The server is running service pack6 and exchange has service pack4 installed. Any suggestions would be much appreciated.

The key ones re your prob are 1 & 2 - your database is inconsistent and will not start. Get the bad news over with first... You do have good online backups, don't you?

Did you see any -1018 errors? This usually indicates a serious prob, in that the data written to the disk is not the same as the data read back from the disk. If you have a good backup routine, it'd probably be easier to restore an older IS and replay the logs. You'll find that current backups won't work now either - databaseconsistency is checked before backup starts, and backup fails if the IS won't start.

Having said that, plug the event ID numbers into Technet and see what it comes up with. You may get away with just running an isinteg -patch, but check the MS Exchange Disaster Recovery docs for more detailed info.

There are only two links above - MS made them huge with the latest site reorganisation.

Comment regarding online backups was for a reason - online backups (while services are running) checks the consistency of the databases during the backup. Offline backup (stop services and copy the .edb and .log files) do not. All you have is a bunch of files that may or may not work when you try to start them. MS very much prefers online backups; it reduces the amount of work the PSS people have to do.
